IMPROVEMENT IN HOlSTING APPARATUS.

Speciiioation forming part of Letters Patent No. 121,463, dated December 5,1871.

To all whom it may concern:

Be it known that I, J ESSE NICHOLSON, of Monticello, in the county-of White and State of Indiana, have invented a new and useful Improvement in Apparatus' for Loading Ooal on Railway Cars, of which the following is a specification, reference being had to the accompanying drawing.

The object of my invention is to load locomotive-tenders, Sac., momentarily upon their arrival at a Station, thereby causing but a moments delay; and my invention consists in the construction of the box in which the coal is hoisted and from which it is dumped into the tend er; and it also consists in the combination of said box with the apparatus with which it is hoisted.

To enable those skilled in the art to understand how to manufacture and use my invention, I will describe the same with particularity, using the same letters to represent the corresponding parts in the diiferent iigures in the accompanying drawing, in which- Figure l represents a side elevation of my hoisting apparatus with the coal-box attached; Fig. 2, an end elevation, with a locomotive hoisting` the coal-box 5 Fig. 3, a side elevation of the box detached 5 and Fig. 4, an end view of the same.

A is the coal-box, which is made suiiiciently large to hold coal enough to ll the tender. This box is made in two parts, each part being hinged at its top to the bail B by the hinges O. D are hooks for holding the box closed at the bottom when loaded, and E is a rod pivoted to the box so as to fall above the ends of one set of the hooks D, as clearly shown in Figs. 3 and 4, to prevent the hooks from unclasping. F F are chains extending from the rings H H to the sides of the box at or near its top; the bail of the box also passes through the rings. I is a chain, which is attached to the pivotal rod E, and is used to remove it from the ends of the hooks D when it is desired to dump the coal from the box, as hereafter described. J is a strong substantial frame, built over the railway track in such a manner that the box of coal canbe hoisted and swung over the tender and its contents dumped into it, as hereafter described. Kis the hoisting-chain for hoisting the coal. It is rigidly attached to the frame atL, and, passing over the pulleys M, is wound on the drum N. O is a loose pulley running on the hoistingchain K, as shown. P are hooks suspended from this loose pulley, and are used to hook into the rings H H for hoisting the box. Q is a windlass, with a ratchet and pawl R to hold it at any desired place. S is a rope, which is Wound on said windlass. T is a rigid arm or piece passing around the hooks P to hold them in position when unhooked from the rings H H. One end of said rigid piece is attached to the rope S, and it is supported by the small roller U, which rolls out on a track, V, when the box is allowed to swing out over the tender, as hereafter described. W is a rod attached to the pawl R to operate it, and a isa rope attached to the windlass Q for the purpose of revolving it to and up the rope S and Swingin g the coal-box back to the position shown in Fig. 1. bis a shaft carrying two drums, N and N. c is a chain that winds over the drum N f and dis a hook attached to said chain, to which the power is applied for hoisting the coal. e e are the railway tracks, andj'f tracks for the trucks on which the coal-box is carried to be iilled with coal and brought back, ready to be hoisted.

My apparatus operates as follows: The coal box, being placed on a suitable truck, is iilled with coal from a bin and rolled beneath the frame J. The hooks l) are then hooked into the rings H H. Vhen the locomotive comes upon the track c e to take on coal the hook d is hooked to the locomotive, and, as the locomotive moves along so as to bring thetender opposite the coal-box, the chain c turns the shaft b and raises the coal-box as high as the top ofthe tender. The hook d, just at that point, unhooks from the locomotive and the pawl t' holds the coal suspended. The operator then raises the pawl It by means of the rod W attached thereto, and the coal-box Swin gs out over the tender. The chain becomes taut as the coal-box swin gs out and raises the pivoted rod E, thereby releasing the hooks D so that theyunlock,and thebox swings open at the bottom and dumps the coal into the tender. The bail of the box, passing through the rings H H, takes the weight of the box from the chains F F just as theyhave opened the box sufiicient to deposit the coal. The operator by then pulling the rope a turns the Windlass Q and, by winding thereon the rope S, swin gs the coal-box back over its truck, when, by raising the pawl i, it drops upon the truck, winding up the chain c to elevate another load.

The hook d is so constructed that it is unhooked at any given point by means of a cord attached thereto. This hook is also of my invention, and is fully described in an application for a patent of even date herewith.

It'will be observed that by having several of these coal-boxes, any number of locomotives can take coal from the same stand nearly as fast as they can be driven up, but a slight delay being parts and hinged at the top, as and for the purrcquired. By constructing the box so that it pose described. swings open at the bottom it is necessary to raise 2. The combination of said coal-box and the it only as high as the top of the tender, and it hoisting apparatus above described, when con- Will also fill the tender and even heap it full structed substantially as described and shown. Without spilling` the coal. JESSE NICHOLSON.
